Title: Improvements in or relating to automatic circuit-breakers
IPC: H01H71/24
Filed: 1945-09-19
Abstract: 599,407. Automatic circuit - breakers. THEUNISSEN, F. J. M. Sept. 19,1945, No. 24286. Convention date, April 23, 1940. [Class 38(v)] An automatic circuit-breaker comprises a release coil 9, the armature or armatures of which are adapted on overload to trip the breaker and to act directly on the movable contact 2 independently of the tripping mechanism. On a moderate overload, a bimetallic strip 8 acts on arm 10 of the pawl 7, thereby releasing a lever 5 which is moved counter-clockwise by a spring 4 until the centre-line of the spring moves past pivot 3a of the movable contact 2 which is then snapped open. If a heavy overload occurs immediately, the armature 11 moves upwards and trips the pawl 7 through an extension 14, Fig. 1, and, on a short-circuit, the armature 11 moves a non-magnetic plunger 12 to open positively the circuit. In Fig. 2, a heavy overload causes an auxiliary armature 15 to move downwards to trip the breaker through lever 17, and a short-circuit causes tripping and also causes the plunger 12, carrying the main armature 11, to open the circuit. In a modification, Fig. 3 (not shown), the lever 17 is replaced by a sliding rod which is acted upon by a conical armature to release the pawl.

Title: Improvements in or relating to vacuum distillation
IPC: B01D3/10
Filed: 1927-09-21
Abstract: 303,078. Burch, C. H., Bancroft, F. E., and Metropolitan-Vickers Electrical Co., Ltd. Sept. 21, 1927. Column stills and rectifiers; evaporators and condensers in structural combination. - Organic liquids e.g. oils are distilled in a highly evacuated chamber and are condensed in a surface located with respect to the surface of the liquid to be distilled so that the distance travelled by a particle of vapour in its passage to the condensing surface is commensurate with the mean face path of a molecule of the vapour in the residual gas, i.e. mercury vapour, in the chamber. If the liquid to be distilled is of the kind that distills without spitting and without the formation of bubbles within the liquid e.g. oils, paraffin wax, and " vaseline," the apparatus is constructed so that substantially all the vapour particles impinge directly on the condensing surfaces as shown in Fig. 3 but if the liquid on distillation bursts into foam as e.g. acetone, water, petrol, benzol, &c. baffles are arranged between the liquid and the condensing surface as shown in Fig. 5. A highly evacuated chamber 15, Fig. 3 contains a series of trays 10 provided with baffles over which, the liquid circulates in succession, the trays being heated by hot fluid flowing through pipes 26. Over each tray is arranged a condensing surface 23 cooled by liquid circulating through pipes 25, the liquid also flowing through a jacket 27 around the walls of the chamber. The condensate flows down the inclined surfaces 23 and collects at the bottom of the vessel but a modification is described in which the condensate from each tray is collected separately. In the modification shown in Fig. 5 the chamber is of cylindrical form and its walls form the condensing surface being cooled by a jacket 53. The liquid is delivered through a trap 41 to a series of trays 42 over which it flows in a tortuous path guided by webs 43. The trays are supported on a central tube 45 through which heating fluid is passed or they may be heated electrically. A baffle 46 having a depending rim 47 is disposed above the top tray and is heated to the same temperature so that no vapour condenses thereon. In a plant for distilling oil according to the process the crude topped oil stored in a tank 100, Fig. 7 is pumped through a preheater 102 to a preliminary degassing chamber 104, and second degassing chamber 106 where it is heated under reduced pressure while flowing down spiral plates 114. The oil then enters the first distilling apparatus 116 which is of the kind described in Fig. 6 and is evacuated by a line 117 leading to the high vacuum line 118. The residual oil passes through three similar chambers 142, 157, 164 connected to diffusion pumps 145, 158, 161, the condensate from each chamber being collected in receivers 136, 153, 160, 165. The temperatures of the distilling chambers are indicated by thermo junctions connected to a multi-point switch 177 and pyrometer 176. Specifications 30658/97, 4966/98, 4604/09, 6397/09, and 27500/10 are referred to.

In an arrangement for the simultaneous recording of the refractive index and its derivative in a stratified solution the latter is contained in a cell having a prismatic part horizontally deflecting light from a vertical illuminated slit to form a record of the refractive index distribution, and a plano-parallel part for the determination of the derivative of the refractive index distribution by means of a horizontal illuminated slit, a slit inclined thereto and placed beyond the cell and an astigmatic lens forming in one direction an image of the cell and in the other an image of the inclined slit on a common plane. As shown, the cell comprises a portion A containing the stratified solution and through a part of which a light beam # can pass for recording the derivative curve. Separated from the portion A by an inclined plane parallel transparent partition is a portion B containing a standard medium of uniform density. A beam from a vertical slit is horizontally displaced by the liquids in accordance with the difference of refractive index between the liquids in portions A and B. A number of alternative cells all having prismatic portions are described and the deflections of the beam α may be effected by directing it at grazing incidence from a surface of the solution, the resulting angles of reflection depending on the refractive index of the stratum of solution on which the light is incident. The horizontal and vertical slits are used simultaneously, the beams being confined to their appropriate paths by means of polarizers or suitable stops.

Abstract: 701,835. Electric analogue calculating systems. MACKAY, D. M. April 20, 1949 [April 22, 1948], No. 24990/52. Divided out of 701,781. Class 37 Electronic computing apparatus comprises a source of electrons within a cylindrical electrode surrounded by a coaxial field coil energized by a current representing an input variable and  a feedback system which automatically controls the electrode potential to maintain the electron current at a predetermined small value so that the potential represents the square of the input value ; alternatively the electrode potential represents the input variable and the feedback system maintains the required electron, current level by controlling the energizing current of the field coil to a value representing the square root of the input variable. In Fig. 1 a low velocity electron stream 11 is surrounded by a cylindrical electrode 12 and a coaxial solenoid 13 energized by a current representing the input variable. The arrival of electrons at the positively charged, electrode 12 produces a fall in its potential which is applied to the input of a sign changing D.C. amplifier 14 whose output is connected to reduce the potential between the electrode and the electron source and also reduce the electron current. This reduction corresponding- ly increases the electrode potential and thus the electron current which is effectively stabilised to a predetermined small value, at which the electrode potential represents the square of the input variable. The electrons may be derived from an emitting cathode along the axis of the cylindrical electrode.  In a modification, Fig. 2 (not shown) the feedback amplifier may be a cathode follower whose input is derived from the electron current and whose cathode output is superimposed on the electrode voltage to regulate the electron current to the required value. If the electrode is supplied with a voltage dependent on the input variable, and the field coil energization is controlled by the feedback circuit to regulate the electron current, the field current is dependent on the square root of the input variable. Specification 701,781 is referred to.
